The answer is disgusting, little sister should be prepared.

After the runny nose comes out, it will dry up between the nose and mouth if it is not wiped. If you don't wipe it for a long time, it will produce a dry runny nose: a big runny nose,

Because the nose scabs and loses moisture, the lower end will be tilted, curved like bean sprouts, and translucent in color. If fried with bean sprouts, it won't be picked out. A dirty word used to describe people.
